I want to get into OW but I'm scared of my lack of knowledge.

I'm back into aim training and I want to play aim heavy games as I've been really bored of playing tactical FPS games as they aren't really aim intensive and they are mostly infested with cheaters (especially Siege).

I already play Apex and have been playing for a long time but I also want to get into OW since it seems like it's REALLY aim intensive.

However, I have zero knowledge about the game, never have played before, and none of my friends have played it in the past. And I'm scared of how ''far behind'' I am compared to others.

How can I get into this game without tilting my teammates and learn how to play fast?
